English Translation

Good morning, the sparkly morning sun is a golden spotlight on my whole body
Tehehe, My heart has a premonition of good things to come

How many centimeters is the soul? (I want to know) What kind of shape is it? (Circle, X, square???)
I dunno, but its the place (a warm place) I feel "love" (Correct!)

So, let's go search for and meet our number one (Let's go)
School - sound - song - tea - dessert
Even the hundredth number one is number one
A full heart, a full tummy (is happiness) to satisfaction, together... we grin

There's isn't just one number one

Good night, goodbye today, the starry sky is an indigo-colored blanket
Though there's a bit of a painful squeeze inside my heart

The scabs from yesterday (Painful things) May they disappear before I know it (Abra Cadabra!)
A brand new beginning is (coming suddenly) endless (C'mon!)

Tomorrow too, let's hug with all our might our number one (tightly)

Person - dog - wind - flower - path
Even the thousandth number one is number one
With a full heart, toast our dreams (Do your best) Chase after them and you'll be fine even if you fall

(Keep on Keep on Singing Songs)
(Keep on Keep on)

When you think "The best", you have to feel "the moment", and "now"
Every one was born to make these things!? To have a heart!!

Always, ICHIBAN is No. 1 We are all No. 1 (Yahoo!)
We have fun giving it our all
Even the ten billionth number one is a treasure
To meet by chance, to come to love someone, (Believe) to hug, to let go
Ah, (See you, Good-bye) Until we meet again (Hello) it's a repetition of happiness
No matter how many number ones there are, there's no substitutes for any of them
A full heart, a full tummy (Thank you) to satisfaction, always, always... we grin

It's infinite, the power of number one
There isn't just one number one
